Specifications of the BraggTune
General specifications
| Model | FBGTM1-914 |
|---|---|
| FBG wavelength tuning range with single phase mask 1 | 500 – 2500 nm |
| Length of grating with tunable writing 2,3 | < 25 mm3 |
| Maximum grating length for behind the phase mask (BPM) writing 4 | 120 mm |
| FBG length | 10 mm 5 – > 25 mm 6 |
| Strain tuning of FBG before writing 7 | 5% |
| Max dimensions | depend on unit option |
| Grating tilt range | 0 – 45 º |
1 The tuning range can be shifted upon demand.
2 Standard FBG length is 10 mm.
3 With Option –LG (Maximum phase mask length is 25 mm for any Bragg Tune).
4 With Option -BPM.
5Guaranteed for minimum coherence length of laser of 5 mm. FBG length at wavelength <600 nm is limited by coherence length of laser.
6Guaranteed for minimum coherence length of laser of >>10 mm (SLM laser) and maximum phase mask length of 25 mm, and limited length at wavelengths <800 nm.
7For use with hard coated fibers such as with Ormocer or Polyimide, assuming that the fiber survives the strain.
